In this pyramid of scientific and engineering effort there will be
found requirements for the services of almost every type of
scientist and engineer to a greater or less degree. In the
forefront, of course, are the aerospace and astronautical engineers
but the development of the Saturn launching vehicle has also
enlisted the cooperation of civil, mechanical, electrical,
metallurgical, chemical, automotive, structural, radio, and
electronics engineers. Much of their work relates to ground
handling equipment, special automotive and barge equipment,
checkout equipment, and all the other devices needed to support the
design, construction, testing, launching, and data gathering.[47]
